Alex,
Myself and several others here at Emulex maintain the code. The
recommendations look fine. Feel free to post something if you beat us
to the work.

In similar code, mpt3sas and lockless hpsa just call get_cpu_mask()
inside the loop:
cpu = cpumask_first(cpu_online_mask);
for (i = 0; i < h->msix_vector; i++) {
rc = irq_set_affinity_hint(h->intr[i], get_cpu_mask(cpu));
cpu = cpumask_next(cpu, cpu_online_mask);
}
get_cpu_mask() uses the global cpu_bit_bitmap array, which is declared
in kernel/cpu.c:
extern const unsigned long
cpu_bit_bitmap[BITS_PER_LONG+1][BITS_TO_LONGS(NR_CPUS)];
That approach should work for lpfc.
Ok, good deal. Thanks for the info, Robert. Do you know who the
current maintainer is for this code? Would that be you? I included the
two authors that get_maintainer reported, but haven't heard from them.
I like this approach and don't mind implementing it myself, but I'd like
to confirm that whoever would be responsible for merging the code is ok
with the change before going forward. Of course, if the code has been
orphaned, then I guess we just write away :)
Thanks again for the help!
- Alex
